Located right behind the corner out side of the Vatican (follow Via Leone IV and then turn) You can choose the container beginning from 2eur for the small one and so on. The scoops are XXL!!! The ice cream is very delicious. Try the walnut! Yummy! Worth the little standing in line to get an ice cream...
Do yourself a favor - If you are in the area of the Vatican stop over and taste this gelato. You won't be disappointed. Be prepared to wait!
It is an amazing experience, this place is a must see when in Rome. The staff is very welcoming and nice. You might have to wait a bit for your turn but it is worth it. Once you taste you will know why people are lined up :)
